Title: Improvements relating to rotary kilns
IPC: F27B7/40
Filed: 1936-08-06
Abstract: 479,459. Rotary kilns. JORGENSEIN, M. VOGEL-. Aug. 6,1936, No. 21702. [Class 51 (ii)] In a rotary kiln heated by a flame directed axially along the kiln from the outlet end in countercurrent to the charge, secondary combustion air is admitted to the kiln through apertures controlled by dampers which automatically adjust themselves, as the kiln rotates, so that admission of air close to the surface of the charge, and consequent entrainment of dust, is substantially avoided. The invention is described in connection with a kiln provided, around its discharge end, with a series of cooling tubes having apertures 3 in their ends for the admission of air which, after cooling the charge, passes to the kiln as secondary combustion air. The apertures 3 are controlled by sectorshaped pivoted dampers 1 which, as the tubes rotate with the kiln, function under the action of gravity to shut off those inlets which would pass the air to the kiln close to the surface of the charge. Fig. 3 shows a construction in which the damper 1 is integral with closing member 7 for the discharge outlet 6 and with a ring 4 on which a weight 5 can be adjusted to vary the timing of the opening and closing of the damper. In a further modification, a roller on each damper co-operates with a curved guide rail so that the damper is kept open for a longer period when on the side of the kiln opposite to that on which the charge banks up.

Abstract: 388,050. Coating surfaces. WADE, M. C., 6, Broadlands. Road, and SHARPE, W. S., 12, New Court, Carey Street, both in London, (Representatives of WADE, H.).- (Bonniksen, C. W.; Wald Hotel, Post Unterach, Mondsee, Austria.) Aug. 13, 1931, No. 22921. [Class 95.] Varnish films are dried by treating the wet film with a liquid which is immisible with the varnish but absorbs the solvent from the varnish solution. The varnish solution may be a solution of a cellulose ester, for example celluloid in acetone. The treating liquid may be a vegetable oil such as castor oil, oil of cloves or oil of peppermint or petrol, benzene, toluene, alcohol or water. The solvent may be separated from the used treating liquid by fractional evaporation and the purified liquids may be used cyclically. Contained gases such as air may be removed from the varnish solution and treating liquid before use. The celluloid layer from which the camphor has been removed by the treating liquid may be treated in a bath containing a plasticizer such as diethyl phthalate. A film 13 of varnish solution falls from a slot 12 in a hopper 11 on to a sheet of glass 15 fed by rollers 16, 17, the rate of feed of the glass sheet being slightly greater than the rate of fall of the solution. Excess solution is received by a roller 14 from which it is removed by a doctor 20 and collected for re-use. The coated sheets are lowered by a conveyer 18 at a slight angle into a bath 19 through which the treating liquid circulates at a temperature of about 35‹ C. After emerging from the bath 19, the sheet preferably passes into a second bath of treating liquid at about 80‹ C. to remove the final traces of solvent and thence into a steam heated oven, after which excess treating liquid is' removed by rubber covered squeegee rollers.

Title: Improvements in or relating to electric oil switches
IPC: F16C33/49
Filed: 1919-09-09
Abstract: 165,117. Victoria Falls & Transvaal Power Co., Ltd., and Price, B. Sept. 9, 1919. Oil switches; switches, quick-break.-In an oilbreak switch in which the are is driven out in an explosion chamber enclosing the fixed contact the oil pressure in the explosion chamber is increased to augment the pressure of the quenching jet by means which restrict the passage of the oil from the explosion chamber to the container. In the form shown in Fig. 3, the conical orifice c through which the movable contact j passes into and out of the explosion chamber containing the fixed contact l is provided with two hinged flaps g which are pushed aside when the contact enters the chamber, as shown, but when the contact passes through the orifice the rush of oil shuts the flaps and closes the orifice except for a small opening formed by cut-away parts g in the meeting edges of the flap. Through this restricted opening the oil is forced at an increased pressure to quench the arc. In the form shown in Fig. 4 when the contact is withdrawn the orifice is closed except for small passages s bv a ball which rolls into a seating r in the upper end of the orifice which is so shaped as to produce in conjunction with the movable contact a suction effect on the oil and increase its velocitv. In the form shown in Fig. 8, the movable contact member is hollow and provided with a transverse passage t of restricted area.; during the downwards movement of the contact member the passage t is closed by the parallel walls of the orifice whereby pressure is stored in the explosion chamber this pressure serving to ferce the oil with great pressure into the arc and through the tubular contact when the passage t is carried below the orifice. In the construction shown in Fig. 9 the movable contact is arranged to move, when released, under the action of a spring and accelerated by the explosion, independently of the operating gear. The movable contact is secured to a sleeve in the spindle u and is acted upon by a coiled spring tending to bring it to the off position; it is connected to the terminal 3 by rubbing brush contacts 1 secured to a projection 2 of the terminal. The contact member at the part where it passes into the explosion chamber is shaped concentric with its axis of movement. The switch is brought to the closed position and held there by raising the hinged catch 7a on the end of the pivoted link 8 through link 10 and bevel gearing 12 operated by an external hand wheel; the catch 7<a> drives the switch-gear through the projection 6. To trip the switch a bell-crank lever is operated through links 17, 19 to push aside the catch 7a. The rebound of the contact member is taken up by a spring dashpot buffer 24.

Abstract: 506,055. Photo-electric apparatus for detecting gases. BERNHEIM, G. W. Aug. 13, 1937, No. 22331. Void. Convention date, Aug. 13,1936. [Class 40 (iii)] Apparatus for the detection of noxious gases comprises means for projecting light from a single source through two containers 4, 5 side by side, each enclosing a translucent screen impregnated with a reagent which changes its colour or opacity on exposure to a gas to be detected. One of these containers is sealed, and the other is exposed to the action of external gas by means of tubes 14. The light passes through the two screens on to a photo-electric cell, the sensitive surface of which is divided into two equal parts by a groove or otherwise. In effect, two cells having a common anode are thus provided, and are connected in opposition to an indicator or signalling device 8. The presence of gas which affects the reagent in the open chamber 5 produces a change in the light beam falling on the corresponding sensitive surface of the cell, and thus operates the device 8.
